To 1131 whom it may concern:

Be it known that 1, WILLIAM H. SCHU- BERT, a citizen of the UnitedStates, and a resident of the city of New York, borough of the Bronx, inthe county of Bronx and State of New York, have invented a new andImproved Railway-Car Ventilator, of which the following is a full,clear, and exact description.

Among the principal objects which the present invention has in View are:to provide a ventilator arranged to direct the natural inflow of airentering a carwindow;

to provide means for controlling the disposition or arrangement of theventilator; to provide means for adjusting the ventilator for service;and to simplify ,the construction of ventilators of the characterdescribed.

Dmwings.Figure l'is a side view of a ventilator constructed and arrangedin accordance with the present invention, the same being shown disposedas in service; Fig. 2 is a horizontal section taken as on the line 2-2in Fig. 1, the ventilator being shown as closed; Fig. 3 is a similarView, showing in full lines the ventilator opened to direct the inflowof air toward the rear of a moving car, and in dotted lines thedisposition of the ventilator for directing the'inflow of air toward thefront of the moving car; Fig. 4 is a detail View on an enlarged scale,and in section, the section being taken as on the line 4& in Fig. 1; andFig. 5 is a horizontal section. of a fragment of a railway car body,showing the lower berth in a Pullman car, and the ventilator constructedand arranged in accordance with the present invention, as used inconjunction therewith.

Descrpt0n.As seen in the drawings, the ventilator consists of a seriesof louvers 9, which are pivotally mounted in an elongated frame 10and-between the rails thereof. The louvers 9 are constructed of anysuitable material, that preferred by me being sheet metal, which iscurled at the edge to form a hinge enfoldingthe pins 11, to pivotthereon. The louvers are preferably curved as seen in the drawings andare prevented from swinging outward from the car by a stop bead- 12, theinner edge whereof is correspondingly shaped to form pockets or recessesfor the said louvers. To operate the louvers 9 in unison, there isprovided a continuous bail handle 13, the short sides 14 -when desiredto set the louvers 9 in their operative position. The elongated sides ofthe handle 13 are each pivotally connected by means of short bolts 15with extended lugs 16, one of which is extended from the lnner side ofeach of the said louvers.

The ventilator is provided with a short louver 17, at what may be termedthe rear end thereof. The lug 18, with which this louver is provided'toform a pivot connection with the handle 13, is set out from the back ofthe said louver. This permits, as seen best in Fig. 2 of the drawings,the folding of the louver 19 upon the louver 17 to close the rearmostopening of the ventilator, when the same is placed in closed position.

To adjust the frame 10 to window openings of various sizes, there isfurnished, an extension stile 20. The stile 20 is slidably mounted inthe frame 10 and inone of the end stiles thereof by a bail loop 21, thestraight ends 22 whereof extend through holes formed in the end rail ofthe frame 10'.

When placing the ventilator in service, the bail loop is moved tocontract the stile 20 on the frame 10 to permit the frame passing thewindow sash stop 23. When the frame is in position, the bail loop 21 isthen moved to extend the stile 20 to fit the grooves formed by thewindow sash stops.

Operation.The frame 10 is of any desired height, it being intended foruse principally as ventilators for Pullman car windows. The height ofthe frame is regulated by the lift of the window. The present ventilatoris peculiarly adapted for employ ment in ventilating the space betweenthe upper and lower berths of sleeping cars and is intended to beinstalled when the berth is made up. As a rule, these berths arearranged so that the sleeper rests in the berth with his head in thedirection of the travel of the car. If this arrangement is followed, theventilatoris installed with the hinges of the louvers in relativelyforward position, so that each of the louvers will swing away from thedirection of travel of the car. It will be noted that the louvers hereindescribed, open within the car and do not extend beyond the side of thebody. Therefore the operation is to direct the natural inflow of air andnot to induce a current of air by capturing and deflecting inward theair through which the car is passing. The ventilator having beeninstalled, if the per- .continue the movement of the handle sonoccupying the berth desires, he may by v grasping the nearest side 14 ofthe handle 13, move the louvers 9 to the position shown in Fig. 3, orany mbdified angle thereof. If the night is sultry or if for any otherreason, the occupant of the-berth desires that the air be deflectedtoward his head or face, he may 13 and louvers connected therewith untilthe louvers are in substantially the position indicated by dotted linesin said Fig. 3 of the drawings. It will be understood that in anyposition of the louvers, the operation thereof is merely to direct thecurrent of air and not to induce the current. In this way, a modifiedand desired ventilation is insured. By employing the short louver 17,the air coming in through the ventilator is prevented from passingdirectly back to disturb a passenger.

Claim:

A ventilator as characterized comprising 1n a car window; a plurality oflouvers pivotally mounted therein and transverse thereof; a plurality ofpivots for said louvers, said louvers being spaced a distanceapproximately equal the length of said louvers; a bail handle foroperating said louvers, said handle embodying a continuous an elongatedframe adapted for installation v oblong frame, the elongated sides ofwhich
